She's smitten! Jessa Duggar only had eyes for her fiance Ben Seewald while shooting their engagement pictures this week. The 19 Kids and Counting star showed off her husband-to-be (and her new bling!) via Instagram on Monday, Aug. 18.

"Time for some engagement photos!" the 21-year-old reality star captioned one photo. The couple smiled at one another while sitting in front of a tree. "I admire this man with all my heart!" she gushed in a similar black and white snapshot. "@ben_seewald, you're absolutely the best!"

Duggar clearly loves having 19-year-old Seewald on her arm, but having a new ring on her finger doesn't hurt either! "Y'all! I still can't believe it! I'M ENGAGED TO THE MOST AMAZING GUY ON EARTH!" she captioned a third picture, showing off her silver band. "Every time I look down at the ring on my finger...it takes my breath away! I love you, @ben_seewald!"
